The PIP process refers to Pin in pad, which is called PIP for short, and is that solder paste is brushed on a PCB, then a connector is placed on the PCB with the solder paste, and the solder paste is melted at a high temperature, so that the problem that the internal solder paste is heated unevenly exists in the conventional connector.

The overpressure design of the crimping process refers to pressing the soldered ends of the terminals into the PCB. The existing connector is completely attached to the PCB, however, due to the elasticity of the plastic shell of the existing connector, the problem that the fisheye terminal is not pressed in place or is pressed in the crimping process often occurs.
